Abstract: The utility model relates to the hydropower industry, in particular to the industrial production of equipment for the construction of hydroelectric power stations. High-ecological hydroelectric power station containing end derivation nozzle with double cover, which is placed between the horizontally placed Buckthorn turbine with double cover on the same shaft with a generator and underwater pressure pipe, and the building of hydropower plants located on the floodplain near the bed or near the slope of the valley or on the dam Collapse, Near which a storage tank is located in which the river water enters the bypass or pressure pipeline, and from the latter, using a hydraulic siphon, the water is fed into balanced capacity on supports from which water is then directed to the derivation, characterized in that the space between the walls of double covers of turbines and nozzles are filled with argon gas at a pressure of 0.18 Pa or less than a specified value. The circulation of argon gas in the spaces between the walls on the atomizer cover and the turbine is due to the temperature gradient between the continuum (in spaces between the substance covers and air). In the pressure pipeline, under the influence of the action of the electromagnetic field from the injector, an additional local electromagnetic field is created which, in its much higher potential, replaces the field of gravity. This action causes the ejection effect in the pressure pipe (speed of movement of water masses on the value of two times higher than the acceleration due to Earth's gravity).. The electromagnetic field of the nozzle allows to replace gravity field and around the generator. Under the influence of this field, resistance is removed in the bearings, which will allow them to extend their service life considerably. At water flow Q = 166 1 / s at the end of the pressure pipeline 200 mm in diameter under the influence of the electromagnetic field, the average flow velocity at the inlet to the nozzle can be proportional to Vser =105 m / s. Power hydroelectric turbine with a diameter of 600 mm to prepare N = vm = kt (105/2 ( 3.14 ( 0.3) ( 60 = 3344 1 kW or 3.3 MW (where vm - turbine rotation speed, m/min; k - efficiency The operation of a turbine with two generators, which, in the absence of the action of the gravity field can be taken equal to one). At the indicated water velocity in the end portion of the pressure pipeline, which is significantly higher than 90 m/s, the manifestation of the dissociation phenomenon should not be observed. Technical and economic efficiency of the present invention is estimated preserving high environmental safety water body (use a small amount of water and the lack of effects of dissociation), construction and operation efficiency and stability of the achieved level of the station during the passage flood reached the minimum interference and water use Water object. Comparative analysis of the estimated cost of a small hydroelectric power station near. Turia Polyana (Tran Carpathian region) and this utility model on the basis of the specified derivation design showed that it is possible to obtain a saving in material and financial costs by the period of their payback of at least 40 %. This is achieved by reducing the cost of derivation and a significant increase in the production of electric current with the possibility of receiving it almost throughout the year.
